BY WWW United States Patent WATER COOLED CONVEYOR CHUTE William A.Harrison, Carlsbad, N. Mex. Application September 14, 1953, Serial No.379,778 1 Claim. (Cl. 193-38) This invention relates to mining equipmentand more particularly to a new and novel conveyor especially adapted forconveying potash ore.

The primary object of this invention resides in the provision of aconveyor for potash ore adapted to be cooled by a water circulatingsystem associated therewith so as to prevent hot potash ore passingtherethrough from sticking to it and clogging the passages thereof.

Another object of this invention resides in the provision of a watercooled conveyor for potash ore adapted to permit the ore to pass throughit without clogging and thereby require no loss of operation due to thetime necessary for scraping the conveyor thereby eliminating thenecessity for cleaning the side wall passage and thus saving the cost oflabor now required to perform such tasks.

Still further objects and features of the invention reside in theprovision of a water cooled conveyor that is strong and durable, simplein construction and manufacture, capable of being readily constructedout of convenient and suitable materials, and which requires only minorattention and maintenance.

These, together with the various ancillary objects and features of theinvention which will become apparent as the following descriptionproceeds, are attained by this water cooled conveyor chute, a preferredembodiment of which has been illustrated in the accompanying drawings,by way of example only, wherein:

Figure l is a perspective view of the water cooled conveyor chutecomprising the present invention;

Figure 2 is a top plan of the conveyor chute;

Figure 3 is a vertical, sectional view as taken along the plane of line3-3 in Figure 2 and illustrating the construction of the coolingpassages in greatest detail;

Figure 4 is a vertical, sectional view as taken along the plane of line44 in Figure 2 and illustrating the construction of the inlet and outletconnections for the water cooling system; and

Figure 5 is a sectional detail view as taken along the plane of line 5-5in Figure 2.

With continuing reference to the accompanying drawings wherein likereference numerals designate similar parts throughout the various views,reference numeral generally designates the elongated metallic watercooled conveyor chute comprising the present invention. This conveyorchute is formed from an elongated channelshaped member 12 provided witha bottom or lower plate 14 and upwardly extending side walls 16 and 18.Anchor holes as at 20 are formed in the bottom or lower plate 14 and areprovided for more easily attaching the conveyor chute to a platform orother apparatus as may be desired.

Secured to the side walls 16 and 18 in spaced relation relative to thelower plate 14 is an upper plate 22 which terminates as at 24 inwardfrom one end of the channelshaped member 12 to thereby form a platform25 at one end of the conveyor chute 10. End walls 26 and 28 are securedto the upper plate 22 and the lower plate 14 and extend between the sidewalls 16 and 18 to thereby form a closed water cooling chamber 30. It isto be noted that the side walls 16 and 18 extend upwardly above theupper plate 22.

Extending between the upper plate 22 and the lower plate 14 and securedto the end wall 24 and extending almost to but terminating short of theend wall 28 is a partition 32 adapted to form a maze for the fluid as itpasses into the water inlet connection 34 and from the water outletconnection 36 disposed at opposite ends of the maze so formed. Connectedto the water inlet and outlet connections 34 and 36 are inlet and outlethoses 38 and 40 which are connected to a cold Water supply system, notshown, so as to circulate the water through the chamber during operationof the conveyor and thereby prevent hot potash from sticking to thewalls of the conveyor thereby increasing the efficiency of the ore mill.

From the foregoing it is to be understood that the hot potash ore iscarried along the upper plate 22 between the side walls 16 and 18. Thecooling fluid prevents the sticking of the ore to the chute as wouldotherwise occur and thereby it may be more easily processed.Accordingly, since the invention may be readily understood from theforegoing, further description is believed to be unnecessary.

However, since numerous modifications will readily occur to thoseskilled in the art, after a consideration of the foregoing specificationand accompanying drawings, it is not intended to limit the invention tothe exact embodiment shown and described, but all suitable modificationsand equivalents may be readily resorted to.

What is claimed as new is as follows:

A water cooled conveyor chute comprising an elongated body portion ofsubstantially channel shape in cross-section and having anchor holesadjacent one end thereof, an elongated water circulating chamber formedbetween the sides of the body portion of the conveyor with the first endof said chamber adjacent said anchor holes terminating inwardly of saidanchor holes, an elongated partition extending centrally through thewater chamber, said partition having a water passage therethrough at theother end of said chamber, said partition dividing said water chamberinto opposed sides, a water inlet conduit secured to said chambercommunicating with one side of said chamber, and a water outlet conduitsecured to said chamber, communicating with the other side of saidchamber, said conduits being disposed at the first end of said chamberopposite the other end of said chamber having the water passagetherethrough.
